☛
Note
In the event that the RAID controller needs to be
replaced, the current drive geometry will be restored
from the configuration on disk (COD).
Using RAID EzAssist
m Caution
Configuration will destroy the data that already exists
on all SCSI disk drives cabled to a SCSI channel
embedded on a system board if the disks can be
controlled by the AcceleRAID controller in a SISL
configuration. If an operating system or existing data
resides on a SCSI drive already installed in such a
system, a full backup must be performed on these
drives prior to this installation.
RAID EzAssist, the on-board BIOS Configuration Utility is used to build
several types of RAID configurations. Since this is a Quick Installation
Guide, only the Automatic Configuration option will be described here.
The following limitations apply to Automatic Configuration:
• Only one array will be configured using the Automatic Configuration
option.
• All drives being controlled by the AcceleRAID board can be different
sizes, but will all be formatted to the size of the smallest disk controlled
by the AcceleRAID board.
• A maximum of 7 drives can be configured into an array using
Automatic Configuration. Any additional drives will become hot
spares. The drives with the largest capacity (if mixed drive sizes are
used) will be the drives selected to become hot spares.
